Came home after work to find out our AC had gone out. Called Brennan H/C and Billy went out of his way after hours to come over to try to get it working. It wasn't a quick easy, fix so they came out next morning with the parts they needed and got it working! Great Service! Would Highly recommend anyone that wants local, quality work.
I had them install a air conditioning unit for our home and it only stays charged for one year. I’ve paid them $1000’s to recharge the unit and they dont stand behind any work. They say its normal to have all the fittings leak every year. Terrible buisness.
I had major water damage in the house with the existing furnace being submerged. Pat came right over to inspect the issue. He was so wonderful and very nice to work with! The next morning Chad was over to install a new furnace and air conditioner and to repair the ducting that was damaged. They were absolutely fantastic! It was one of the best experiences considering the circumstances and they will always be my go to from this point on!
I Called and spoke with Pat about a garage heater install. He made time for me just a few minutes, and he followed me to the garage. Pat only asked a few questions, like where did I want it, and anything special on the vent. Straight up the wall and out the back of the garage. Wow, that is what he did, and it is great. They even used cluck that matches the sideing. I am very happy with the job and workmanship. Excellent work.
I have used Brennan at both our store and at home to service our Heat and AC systems for over 25 years. Staff is knowledgeable and personable. They have serviced our roof system when it was -10. The tech was a Popsicle when done but he got our heat going! Fairly priced and reliable. I appreciate the good work.
